The ONLY Mobil 1 that has enough ZDDP is 15W-50. (not 20W-50, not 10W-30). Check Mobil1's website, they give it to you in ZN/PH. You want at least 1200ppm (or it may say .12). As you will see
all the rest of the oils (with API-SM standard) are now 800ppm (or .08).
Conventional oil is no better, if it has API-SM on it-it's bad. You want Valvoline VR-1, any weight is ok. (not regular Valvoline though).

I invite you to do a search on ZDDP, it has been discussed alot in a few threads on this site. It's scary how many others don't know about this, especially since it affects our old car engines in a very bad way. Heck, I didn't know until about 6-8 months ago and the API- SM standard has been out for about 4 years. Your father's old trusty oil is not the same anymore! (unless it's been in the barn for about 5 years)
